Step-by-step explanation:
x=c-y. / x=py/q
y=c-x. / y=xq/p
Answer:
Below in bold.
Step-by-step explanation:
x + y = c
x/y = p/q
From the first equation y = c - x
So substituting in the second equation:
x / c -x = p/q
pc - px = qx
qx + px = pc
x = pc /(p +q)
Now substitute for x in the first equation:
pc /(p +q) + y = c
y = c - pc/ (p + q)
y = pc + qc - pc)/ (p + q)
y = qc / (p+ q).
